MALELANE, South Africa, Dec 14, 2012 (AFP) - The South African teed off on the 10th hole, making four birdies and an eagle from the 15th to the second at the 6,671-metre Leopard Creek Estate course which borders the world-famous Kruger National Park.
Two more birdies later and he was in a share of the lead, tied with first round leader Bourdy from France at 13 under par.
"It was there for the taking and luckily enough I took advantage early on," said the 28-year-old South African.
"I made a couple around the turn and could have been a few more there, but we can't get too greedy. All in all a very good round and I've put myself in a very good position to compete."
After winning in Thailand last week, the 2010 Masters champion is on a roll hoping to win his second title at Leopard Creek having been runner-up four time.
Bourdy bogeyed the par-four third, but his six birdies and eagle on the par-four sixth nevertheless helped him card an seven-under-par 65 -- one stroke better than his Thursday round.
"I'm feeling great and I played two good rounds. Many birdie opportunities again today, especially on the first holes," said the 30-year-old.
"I chipped in for eagle on six. It's driveable there, but I missed the green on the right side ... and had a lob shot and it was the perfect shot. It's the kind of shot you can't do all the time, but this one was the right one," he added.
"My game was again solid, and I made just one bogey today, so it was a great round again. It's tough all week -- you have to do the job over four rounds and that is difficult."
Third-placed South African Darren Fichardt trailed the leaders by four strokes after shooting four birdies and no bogeys to card four-under-par 68.
"I'm just going to go out and play my game and see what happens. I don't want to push it too hard because I'm happy with nine-under-par; what I'm doing already seems to be working pretty well -- just hitting fairways and greens -- so I'll be looking for more of the same," said the 37-year-old three-time European Tour title winner.
